VENTILATING APPARATUS FOR CLOSET-BOWLS.

To all whom it may concern Be it known that I, ARTHUR W. LUCAS, a citizen of the United States, residing at Fremont, in the county of Dodge and State of Nebraska, have invented certain new and useful Improvements in Ventilating Apparatus for Closet-Bowls, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to ventilating apparatus for closet bowls and has for its principal object simple and eflicient means for withdrawing the obnoxious fumes. v

A further object of the invention is to provide a bowl having upon the sides thereof chambered enlargements, each having a plurality of openings communicating with .the interior of the bowl and an enlarged opening communicating with the exterior of the bowl and permitting of the insertion of a suction pipe into the chamber.

The invention consists in the construction and arrangement of the various parts as my device is hereinafter more fullyset forth and as shown in the accompanying drawin s, in whichigure 1 is a side elevation, partly in section, and partially diagrammatic, showing a closet embodying my invention;

Fig. 2 is a vertical sectional view taken through the bowl;

Fig. 3 is a front elevation, partially in section, of the bowl, and

Fig. 4 is an enlar ed detail sectional view showing the mounting of the pipe within the chamber.

Referring now more particularly to the drawings, the numeral indicates a closet bowl of any desired construction, the characters T and L representing the top of the bowl and the normal water level therein, respectively.

In accordance with my invention I provide upon each side of the bowl 10 an enlargement 11 extending horizontally and chambered, as at 12. The chamber 12 is in communication with the interior of the bowl in a series of spaced points, as indicated at 13. The chamber 12 is preferably oval in shape and the openings 13 communicate the upper and lower ends thereof.

The chamber 12 is provided at its rear end with an enlarged o ening exteriorly of the bowland permittlng of the insertion of a lead pi e 15 having its forward end closed. he pipe 15 within the Specification of Letters Patent.

engage the side walls of the chamber 12 and is of such size that it does not completely fill the chamber 12,, but is spaced therefrom at the upper and lower ends, the oval formed {lay the pipe being shorter in its major axis an 15 is provided in its side walls with slotted opemngs 16 communicating with the space thus formed and consequently communicatmg with the interior of the bowl 10.

The pipes 15 are preferably joined and communicate with one end of an exhaust p1pe 16*, the opposite end of which communicates with a; casing 18 within which is arranged a motor driven suction fan 19, the

' chamber is flattened so that its side walls I the oval of the chamber 12. The pipe speed of which is controlled through me dium of a rheostat 20 located at a convenient pomt or by any other suitable means. The opposite end of the casing 18 communicates with an exhaust pipe 21 opening to the at mosphere or into the usual soil ipe vent V. Within this exhaust pipe 21 preferably arrange a check valve 22 which is closed when the fan 19 is not in operation and which,.accordingly, prevents return of obnoxious odors through the exhaust pipe.

From the foregoin it will be obvious that I have provided a closet bowl construction which is particularly well adapted for use in that it readily permits of the attachment of a suction apparatus for withdrawing from the bowl all obnoxious fumes; and it will likewise be obvious that the construction of the same, as hereinbefore set forth, is capable of some change without departing from the spirit of my invention. I, accordingly, do not limit myself to the specific construction as hereinbefore set forth, except as so limlted by the subjoined claims.

What I claim is: Y

1. In a ventilating apparatus for closet bowls, a bowl having the intermediate portion of its wall, above the water level, formed with an outwardly extending hollow thick- ,ened portion, the bowl being formed at its inner periphery with two series of holes leading into the upper and lower portions of the hollow within the thickened portion of the bowl, a pipe permanently located within the hollow thickened portion and provided at its uppermost and lowermost points with series of perforations, and means for creating suction through said pipe.

2. Ina ventilating apparatus for closet bowls, a bowl having the intermediate por- Q IAOLQQE.

tion of its wall above the water level formed uppermost and lowermost portions of said with an outwardly extended thickened porpipe being formed with perforations, and tion formed hollow to define a chamber, the means for creating suction through said bowl being formed at its inner periphery pipe, the lower serles of holes in the bowl 5 with upper end lower series of holes com-= wall permitting the automatic outlet of any 15 municating with the upper and lower porwater splashing into said chamber. tions of said chamber, a pipe located with- In testimony whereof I hereunto afiix my in said chamber and spaced fromthe uppersignature, most and lowermost portions thereof to 10 leave spaces into which said holes lead, the ARTHUR We LUCAS.
